I got my specifications from the www not from actual measurments. I hope to make actual measurements soon. I still maintain that the wall thickness of screw in barb type fittings and hose is a lot greater than that of schedule M copper tubing and this will permit much greater flow. Besides I do feel that an ultra clean mounting is possible with copper. I am not advocating an all copper plumbing system, rather mostly copper with short sections of silicon tubing to allow slight flexing for alignment and anti vibration. In my case I will only be plumbing to the video card and the chipset, the CPU will be cooled by phase-change. One of my major goals is the routing of electric and cooling in a way that looks like it was a factory design or is completely invisible.
